WebbA. LTP Window The 20 ms pre-post window for LTP induction is much shorter than the time constant for the dissociation of glutamate from NMDARs (109). One explanation of this narrow LTP window is the kinetics of Mg2 unblock of the NMDARs. Using nucleated patches of neocortical py-ramidal neurons, Kampa et al. (50) measured the rate of Webb30 sep. 2008 · The induction and expression of LTP at thalamo–LA synapses is mediated by Ca2+influx through postsynaptic NMDA receptors eventually leading to the recruitment of new AMPA receptors to the postsynaptic membrane (4–7). LTP at cortico–LA synapses is mediated by contrasting mechanisms.

The induction of NMDA receptor-dependent long-term potentiation (LTP) in chemical synapses in the brain occurs via a fairly straightforward mechanism. A substantial and rapid rise in calcium ion concentration inside the postsynaptic cell (or more specifically, within the dendritic spine) is most possibly all that is required to induce LTP. But the mechanism of calcium delivery to the postsynaptic cell in inducing LTP is more complicated. Webb13 jan. 2015 · Given the increased LTP amplitude observed in the dorsal hippocampus of RSR rats, we performed a linear regression between REM sleep quantity and LTP amplitude induced at 10 Hz (Fig. 3E).
